Description
Technical field
It the utility model is related to a kind of trolley with adjustable wheel shaft suitable for manual transportation weight.
Background technology
This trolley with adjustable wheel shaft is known from american documentation literature US 5,118,124.Adjustable wheel shaft
It is set as operating after the loading plate of trolley has loaded, then must tilts and allow it to move.For adjustable wheel
The axle suspension of axle includes three arrays for being mutually pivotable section, and the wherein pivotal point between second segment and the 3rd section is formed by wheel shaft.
Under unloaded state, the 3rd section of axle suspension is locked so that wheel shaft is maintained at resting position, and is made by unlocking the section
Adjustable wheel shaft is set as operating.
During the inclination of trolley, adjustable wheel shaft is moved rearwards, and is then moved towards main frame so that inclined
The comer edge of first stage, loading plate and main frame keeps contacting with ground.Then comer edge is removed from ground, and hand
Stroller is supported on the tilted block on the downside of the rear of main frame, until wheel shaft is supported in terminal position the rear side of framework.Utilize
The power that heavy duty is tilted to needed for moveable position is realized significant reduction by the trolley, user.
The shortcomings that this trolley is, axle suspension has complicated design, it is necessary to lock, and need tilted block so as to
Only each section is just loaded after wheel shaft reaches terminal position.
Utility model content
The purpose of this utility model is to provide a kind of improved trolley with adjustable wheel shaft, so as to completely or partially
Ground eliminates one or more of disadvantages mentioned above.
In order to realize the purpose, first aspect of the present utility model is related to a kind of trolley with adjustable wheel shaft, bag
Include：
Elongated and substantially planar main frame, there is front side and rear side, top and bottom and left side and right side, including
Two or more up-and-down rods being connected with each other；
Loading plate, is fixedly connected to the front side and lower end of main frame, and wherein loading plate and main frame is substantially at a right angle；
Axle suspension, including it is fixedly connected to the rear side of main frame and the rigid body of close lower end；
Wheel shaft, wheel is provided at both ends with, and can be rotatably set on the inside of axle suspension so that wheel shaft remains parallel to main frame
The orientation of frame plane；
Wherein：
The rigid body of axle suspension include wheel shaft under two kinds of different service conditions against low retainer and high retainer,
High retainer is located at than low retainer closer to the position of the rear side of main frame,
Axle suspension includes the guiding piece for being used for guiding wheel shaft on the path between low retainer and high retainer,
It is characterized in that：Guiding piece is implemented as so that on path during guiding wheel shaft, wheel shaft relative to loading plate and
The comer edge of main frame keeps substantially the same distance,
And the path between wherein low retainer and high retainer be relative to plane main frame into 40 to 75 degree angles
The slant path of degree.
This trolley has the advantage that wheel shaft hardly shifts on the ground during inclination, is thus applied to
Power on axle suspension and wheel shaft is minimum.Thus, for example tilted block is no longer needed to use to mitigate the load on axle suspension.Trolley
It can be tilted after all while being supported in comer edge, until wheel shaft reaches high retainer.The axle suspension of this trolley
It can in a straightforward manner implement, and the stability of trolley is improved during heavy duty is tilted.Path is relative to main frame
The advantages of tilted alignment is realized simultaneously is, when trolley in obliquity (generally relative to vertical direction on level ground
With the angles of about 30 to 35 degree) it is mobile when, selected slant path prevent wheel shaft can in the vertical direction movement, thus take turns
Start to upspring as in the past during advancing on the uneven part that axle can be on vertical faces.Due to selected inclination road
Footpath also forces wheel shaft into the slant path at usual angle of inclination, therefore balance of the trolley during having load to advance is entered
One step improves.The fact that this improved basis relies on be, slant path have than trolley load it is mobile during institute
The big angle of usual angle kept.
Trolley may include positioned at the upper end of main frame so as to the handle preferably manipulated by user.If desired, dress
Support plate can be connected for example by nuts and bolt, be detachably connectable to main frame.Therefore, the size and embodiment of loading plate
It can change, and can simply be changed in the case of defective.
Guide profile is more preferably included according to the guiding piece of trolley of the present utility model, guide profile includes being suitable to
To the profile of guiding wheel shaft during wheel shaft is mobile on slant path, and low retainer and high retainer preferably cloth herein
It is set to and guide profile is integrally formed.
This guide profile provides the supporting to wheel shaft in high position, thus during trolley has load to advance, makes wheel
Axle is more stably maintained at the position.
Profile has inclined orientation preferably relative to plane main frame so that the direction of profile is relative to the main frame of plane
Put up the angle of 40 to 75 degree.
Guide profile is, for example, preforming groove or preforming edge, its be arranged in the rigid body of axle suspension or on, and
If desired, low retainer and high retainer are incorporated into wherein.Guide profile guiding wheel shaft low retainer and high retainer it
Between movement so that wheel shaft moves along the profile of guide profile.Therefore, guide profile supporting expected behaviour of the present utility model
Make, i.e., relative to the comer edge of loading plate and main frame, wheel shaft is maintained at substantially the same distance.
Actuator is preferably included according to the axle suspension of trolley of the present utility model, the actuator by wheel shaft be set to
By low retainer.
Actuator applies constant power on wheel shaft so that it is configured to against low under the unloaded state of trolley
Retainer.Actuator can be for example spring, such as compression spring, extension spring or torsionspring.Therefore do not need wheel shaft against
The latch-up structure of low retainer, this simplifies the design of trolley and its use.
According in trolley of the present utility model, it is advantageous that guiding piece includes moveable arm, the connection of its first arm
To rigid body, and wherein wheel shaft is arranged in the second arm internal rotation.
